Cobalt is the offset element in the ninth cavalcade of the periodic table. Information technology is classified every bit a transition metal. Cobalt atoms have 27 electrons and 27 protons with 32 neutrons in the about arable isotope.

Characteristics and Backdrop

Under standard conditions cobalt is a hard, brittle metallic with a bluish-white color. It is 1 of the few elements that is naturally magnetic. It tin can exist easily magnetized and maintains its magnetism at loftier temperatures.

Cobalt is simply somewhat reactive. It reacts slowly with oxygen from the air. It forms many compounds with other elements such as cobalt(II) oxide, cobalt(Ii) fluoride, and cobalt sulfide.

Where is cobalt institute on Earth?

Cobalt is not plant equally a free chemical element, but is institute in minerals in the Earth's crust. Cobalt ores include erythrite, cobaltite, skutterudite, and glaucodot. The bulk of cobalt is mined in Africa and is a byproduct of the mining of other metals including nickel, copper, silver, lead, and iron.

How is cobalt used today?

Most of the cobalt that is mined is used in superalloys which are very resistant to corrosion and are stable at high temperatures.

Cobalt is also used every bit a blue coloring agent in paints, inks, glass, ceramics, and even cosmetics.

Other applications for cobalt include batteries, industrial catalysts, electroplating, and powerful magnets.

How was information technology discovered?

Cobalt was discovered by Swedish chemist George Brandt in 1735. He isolated the element and proved that it was the source of the color in blue glass which previously was thought to be from bismuth.

Cobalt compounds were used throughout aboriginal history past civilizations such as Ancient China and Rome to make blue drinking glass and ceramics.

Cobalt is also important for animal life. The torso uses it to create sure enzymes. It is also a component of the vitamin B₁₂.

Where did cobalt get its name?

Cobalt gets its name from the German language word "kobalt" which means "goblin." Miners gave cobalt ore this proper name equally they were superstitious almost mining the ore.

Isotopes

Cobalt merely has one stable isotope that is plant in nature: cobalt-59.

Oxidation States

Cobalt exists with oxidations states ranging from -3 to +four. The most mutual oxidation states are +2 and +iii.

Interesting Facts most Cobalt

Cobalt was the starting time metallic to be discovered since prehistoric times and the starting time metal with a recorded discoverer.
Cobalt-threescore is used to create gamma rays which are used to treat cancer and to sterilize medical supplies.
Too much or too niggling cobalt in the body can cause health issues.
Small amounts of cobalt are sometimes used in fertilizers.
Nearly of the cobalt used in the The states is imported from other countries.
